FIELD OF THE INVENTION

The present invention relates generally to leashes that mechanically couple a human being to a mobile sports device, such as a surfboard, snowboard, skateboard, wakeboard or bodyboard.

BACKGROUND OF THE INVENTION

Numerous sports devices include a board element upon which a user stands and balances during use. It is often desirable to provide a leash coupling the user to the board element to increase the ease of management and retrieval of the board element. In the prior art a first end of the leash is typically attached to the trailing section of the board element. Board leashes may include a second end having a wrist or ankle strap for attachment to the user's body. The leash is preferably long enough to reduce the likelihood of injury to the user, e.g., a surfer, when the user becomes separated from the board element, while enabling the surfer to readily recover the board element for remounting.

A rail saver comprising a strip of fabric wider than the cord may optionally be provided to protect the board element from damaging contact with the cord. The rail saver may increase undesirable drag that degrades the mobility of the board element.

The prior art provides leashes that enable removal of the leash from the user as desired by the user, while securing the leash to the board by means of a cord knotted about a pin located within a plug assembly. The plug assembly (hereafter “plug”) may be fitted into a recessed area of the board, whereby the plug and its pin are located below a substantially planar top surface of the board. The cord may be untied from the pin to facilitate storage of the sports device. Undesirably, the cord may also be detached from the other leash elements and misplaced between uses of the leash.

The prior art includes attempts to improve leash attachments means. U.S. Pat. No. 5,098,324 discloses a combination rail saver and key holder. U.S. Pat. No. 5,127,861 presents a combination leash attachment and lock for surfboard. U.S. Pat. No. 5,775,965 provides a leash release mechanism for surfboards and the like. U.S. Pat. No. 6,390,872 discloses a surfboard having improved leash plug anchoring. And U.S. Pat. No. 7,013,684 teaches of a cable lock coupling and lock system for surfboards

The entire disclosures of each and every patent mentioned in this present disclosure, to include U.S. Pat. Nos. 5,098,324; 5,127,861; 5,775,965; 6,390,872; and 7,013,684 as noted above, are incorporated herein by reference and for all purposes.
